1998 Lexus GS 400 Friend Put battery in wrong

A friend tried jumpin the car first and so he thought battery was bad and replaced it but he put it in backwards (pos to neg) I came and found the battery in backwards and it was disconnected but he did have it hooked up for a bit (horn blows when battery is in backwards) A bunch of fuses were blown and I replaced them I got the car running but, wipers, radio, seats, power locks and window, ect dont work. I went through all fuses 1 block under hood and 2 inside L&R kick plates, on pass side the dome fuse was blown I replaced and it worked, but the 30 amp for the seat was not and using a test light no power. On driver side I tested the radio fuse which I replaced, their is one under the hood and I tested for power their and I had it but on drivers side radio 2 fuse no power with the key in acc and car running I am confused, well the car runs but cant shift it either so I cant just drive it to a shop without being towed. Any ideas would help. Thanks
